Abstract

The aim was to design and validate a questionnaire pertaining to eating problems in individuals with normal intelligence, within the autism spectrum. The questionnaire was based on literature search and clinical experience. The validation focused on psychometric properties of reliability and validity using a clinical group of individuals with autism spectrum disorders (ASD) (n=57) and a matched, healthy comparison group (n=31). The instrument showed high levels of reliability, convergent and discriminant validity and scaling properties. Logistic regression analyses discerned the single item Simultaneous capacity and the subscale Social situation at mealtime as the best predictors of ASD. In conclusion, the questionnaire is valid and reliable to detect disturbed eating behaviours in individuals with ASD and normal intelligence.
